Abstract

The invention provides a plug flow type reactor based on multi-point feeding. The plug flow type reactor has a water inlet and a water outlet; an H2O2 feeding and mixing integrated module is connectedwith the water inlet, at least one group of O3 / H2O2 feeding integrated module and O3 / H2O2 reaction transition module are sequentially connected below the H2O2 feeding and mixing integrated module; agas-liquid separation module is connected with the water outlet and arranged on the upstream side of the water outlet, and the pipe diameter of the gas-liquid separation module is larger than that ofthe O3 / H2O2 reaction transition module connected with the gas-liquid separation module. The invention has the advantages of high reaction speed, short time, sufficient reaction, low energy consumption, high reaction efficiency, no secondary pollution, simplicity and convenience in operation, small occupied area and high automation level, and the O3 utilization rate reaches 90 percent or above, andthe removal rate of refractory organic pollutants reaches 60 percent or above.

Description

technical field [0001] The application relates to the field of sewage treatment, in particular to a multi-point dosing plug-flow reactor based on high-efficiency ozone oxidation water treatment technology. Background technique [0002] my country's overall wastewater discharge is increasing year by year, and natural water bodies are deteriorating. pH value, chemical oxygen demand (COD), and ammonia nitrogen are the three major pollutants, and chemical oxygen demand (COD) ranks first. In terms of pollution sources, industrial wastewater pollution is the most serious. [0003] The treatment water source of industrial wastewater upgrading and advanced treatment projects is often the effluent treated with biological aerobic treatment, and the ratio of BOD / COD (Biochemical Oxygen Demand / Chemical Oxygen Demand) (referred to as B / C ratio) is already quite low, even lower than 0.1, it is called refractory wastewater. Therefore, in order to further reduce the COD (chemical oxygen ...
